The invention provides a steel tube concrete steel column installation method, which is carried out according to the following steps: Taking the coarse steel bar to make a rotating shaft, and assembling the steel roller on the rotating shaft to form a sliding device. After the civil steel bars are bound, fix the rotating shaft firmly with the reinforcement of the reinforcement cage support column, and the steel roller protrudes from the reinforcement cage contour. During the installation of the box steel column, the inner wall of the box steel column is in contact with the rolling surface of the steel roller. The steel roller rotates with the movement of the box steel column, and the box steel column falls steadily until the installation is completed. The invention also provides a special sliding device for the installation method of the concrete-filled steel tube column, which is composed of a rotating shaft and a steel roller, wherein the rotating shaft is L-angle steel bar, two ends of the rotating shaft are respectively installed with a freely rotating steel roller, the rotating shaft corner is fixedly connected with a sector connector, the sector connector is fixedly connected with the concrete reinforcement cage, the steel roller protrudes from the outer contour of the reinforcement cage, and the rotation direction of the steel roller is the axial direction of the reinforcement cage Direction.

技术介绍
随着工程类型越来越多,结构越来越复杂多样。其中钢管混凝土结构是钢管中填充混凝土而形成的构件,其承载力高、自重轻、塑性好,广泛应用于高层建筑、地下工程和大跨度的支柱等。钢结构施工安装方法根据结构特点不断进步。箱型钢管混凝土柱结构复杂,它是由箱形柱和混凝土柱结合而成。所述箱形柱外周为方形箱体,中间设有十字钢腹板支撑结构,混凝土柱前期要进行钢筋绑轧,钢筋笼固定后,将十字箱套装在钢筋笼上,最后进行混凝土浇筑,完成。钢管混凝土柱结构复杂、安装难度高,箱体内插入钢筋,由于钢筋与箱型钢管混凝土柱腔体内部间隙过小,安装时箱形钢柱内腔体与钢筋接触碰撞,造成已绑扎的钢筋被破坏。同时在钢柱就位过程中,因钢柱内壁与绑扎钢筋外围间隙中,钢柱下移过程中内壁与钢筋产生摩擦和碰撞阻碍钢柱下落,因此,保持箱形钢柱平稳的下落,实现完全套装在钢筋外,操作起来要非常小心,注意多种状况和结构上的配合,这就增加了吊装难度,使安装时间非常长。
